` Specification of Lettersrlatent. Patgnted July 30, 1918,

Application filed July 25, 1914. Serial No. 853,006.

To all whom 'it may concern Be it known that I, JOHN H. Lnwrs, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Locomotive Noiseless Smoke-Consumers, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification. Y

This invention relates to improvements in locomotive noiseless smoke consumers.

As is well known, engineers and firemen on locomotives have considerable difficulty in conversing with each other in the cab of a locomotive while the same is running, due to the great amount of noise. This makes it practically impossible for the men to hear each other unless they shout and, as will be appreciated, it is extremely desirable that the men be able to converse readily in orderk "i causes of the great amount of noise is the air injectors at the sidesof the firebox which ordinarily consist of a plurality of steam nozzles on each side of the V.firebox located within a corresponding number of openings or short pipes leading from the atmosphere to Vthe interior of the irebox through which the air is drawn by the suction induced by the steam.

The main object of my invention is to provide an arrangement whereby the above noted diliiculties are overcome and so arranged that the efiiciency of the air injector is not impaired.

Another and more specific obj ect of my invention is to provide a noiseless smoke consumer so arranged that the intake or intakes for the air are well removed from the firebox.

Another object of the invention is to provide a device of the class above described 'wherein is employed a muffler 0r means for deadening or minimizing the noise where the air is taken into the pipe or pipes before forced into the firebox.

The invention furthermore consists in the improvements in the parts and novel combinations of the parts herein shown, described and claimed.

In the drawing forming a part of this specification, Figure 1 is a. side elevation of the locomotive firebox and boiler showing my improvements in connection therewith, parts being broken away to prevent crowding of the drawing. Fig. 2 is an end elevation of the structure shown in'Fig. l, a portion being broken away at one side to more clearly illustrate some of the details of construction. Fig. 3 is an enlarged detail scctional view showing the steam nozzle in the air pipe. Fig. l is lan enlarged detail Sectional view taken substantially on the line 4 4 of Fig. l.- Fig. 5 is an enlarged detail diametrical sectional vieW of the muier employed at the intake and Fig. 6 is a sectional view taken substantially on the line 6-6 of Fig. 5.

In said drawing, 10 denotes the boiler and ll the rebox both of which are or may be of the usual or well known construction. As customary, the irebox is provided with Va door or opening 1.2, inner shell or wall 13 and outer shell or wall 14. The steam line from the boiler is designated by the reference 15 and the same terminates in a T-l from which leadl pipes 17-17, one to each side of the locomotive. The supply of steam tothe pipes 17-17 is cont-rolled by a globe valve 180. Inasmuch aS the construction on each side of the locomotiveisrthe same,-I will only describe that for one side. Y

On each side, the pipe 17 is extended to point well forward of the fireboX and is fitted with an L 178 to which is secured a short section of pipe or nipple 19 the latter having an L 20 at the bottom from which extends a nozzle2l, the nozzle being pointed toward the firebox and held in position in the T 22 by means of transversely extending pins 23, it being understood that the nipple 19 passes through a nut 24 threaded into the upper side of the T 22. From the T 22 the air pipe line 25 is extended rearwardly and alongrthe side of the rebox, and is provided with a plurality of branch pipes lead-V ing to the interior of the firebox. These branch lines or inlets to the rebox lead from a plurality of Ts 26 and an L 27 at the end of the pipe 25. Each branch or air inlet to the firebox comprises a cylindrical hollow member 28 threaded at its outer end into the respective T or L 26 or 27 as indicated at 29 and at its inner end each, member 28 is provided with a flange 30 which overlaps the flanged end 31 olf a bushing 32 extending betweenthe two walls or shells 13 and 14, each bushing 32 being; also flanged on its outer end as indicated at From the opposite side of the T 22, extends a larger air intake pipe 34 which is bent downwardly as clearly indicated in Fig. l a ud at its outer end has attached thereto a muitlier the latter comprising` a cylindrical member having' a tortuous air passage 36 therein which is formed by means ot' a plurality of oppositely and alternately arranged walls or bailles 3T 37, the interior ot the mntller 35 beingrounded as indicated at 3S opposite the free ends of.' the walls or batiies 37. The two pipe lines 'l'T and are suit,- ably secured together by clamp plates 39 and bolts et() and the T 22 and intake pipe 3l. are suitably secured to the boiler by means of a hanger 4l attached hv a bolt or other suitable device 42.

In operation, when steam is admitted to the pipes 17H17 a jet of steam will flow through each nozzle 2l. in the direction indicated by the arrow a in Fig. 3 and these stean'i jets or nozzles induce a current of air through the intake pines get-34 and inutiers the air passingthrough the latter in the direction indicated by the arrow From the Ts the air is then forced along the pipes 'Z5-25 and through the branch inlet pipes to the interior of the lirebox and in this connection it will be observed that there are no openings on the exterior of the lire-box where the air is forced thereinto so that there is no perceptible noise due to the inrushing mixed air and steam. Furthermore, the air intake is so Copies of this patent may be obtained for ve cents eachLby addressing' the Commissioner at Patents,

far removed from the firebox, and consequently the cab wherein the engineer and fireman stand7 that the amount of'noise is minimized'and particularly on account of the mutliers which deaden or reduce the noise as the air is -drawnfrom the atmosphere.

Although l have herein shown and der scribed what l now consider the preferred embodiment of my improvements, yet the same is merely illustrative and I contemplate all such changes and modifications as come within the scope of the claim appended hereto.

l claim ln a locomotive having' the usual tire box and boiler, the combination with an air pipe line extending along the outside of the fire box and boiler, of a mutller at the intake end of said air pipe line, the muffler being located Wellt'orward ofthe fire box, a steam nozzle extended into said air pipe line adjacent said muffler, and a plurality. of branch inlet pipes extending from said air pipe line through the side of the lire box and to the interior of the latter7 the passage Ways provided for said branch pipes through the side Wall being sealed, whereby air is drawn in entirely by and mixed with the steam in the air pipe near the intake end of the latter and remote from the rear end of the tire box land the mixed'air and steam is injected into the fire box with a minimum of noise at the rear end of the ire box.
